WANSHIELD®63122 Colored – Sand Water – based Polyurethane Mortar Flooring System

1. For All New and Old Concrete Floors: The concrete strength must reach C25 or above, and the pull-out strength should not be lower than 1.5MPa. Thoroughly remove surface stains and loose soil until reaching the solid concrete layer. For any concrete damaged, loosened, or contaminated by substances due to exposure to chemicals, it should be removed until the solid concrete is exposed.
2. For Painted Old Floors: Completely sand off the loose or incompatible old paint coatings. If the underlying concrete surface or a clean, dry, and intact compatible coating is exposed, it can be left without further removal.
3. For Oil-Stained Floors: When the oil stains seriously affect the adhesion of the floor coating to the base surface, the oil-stained floors should be thoroughly cleaned and sanded.
4. For New Concrete Floors: Ensure that the floor has passed the curing period and the moisture content is less than 10%. It is crucial to use mobile sandblasting tools and grinding equipment to treat the concrete surface to achieve the appropriate surface roughness.
5. For other surfaces: If the product is to be used on other substrates, please consult the Technical Department of Yantai Wanhua.
   For detailed instructions on base surface treatment, please consult us to obtain relevant materials.

Construction Conditions
Coating Environment Temperature: 15 – 30°C. The base surface temperature should be at least 3°C higher than the air dew-point temperature.
Coating Environment Humidity: <80%, and the moisture content of the concrete base surface should be less than 10%.
Ventilation Conditions: Ensure that the construction site is well-ventilated and dust-free. However, there should be no strong wind to avoid bringing in dust and affecting the appearance.

Installation:

• Base coat: 1mm (0.9kg/m²), cure 24h @20°C

• Top coat: 3-5mm (6-10kg/m²), trowel-applied

• Walkability: 24h, full cure 7 days

4. Packaging & Storage

Storage: 5-30°C in dry, ventilated area.

• Storage and Transportation Conditions: The paint should be stored in a sealed, dry, cool, and well-ventilated environment at 5 – 30°C, away from high temperatures and fire sources. During transportation, the materials should be stacked steadily, and the carriage environment should be kept dry, enclosed, and protected from moisture and frost.
• Shelf Life: Starting from the production date, under the required storage conditions, the shelf life of the product in its original packaging is 6 months.

5. Safety & Compliance

Before use, carefully read the construction instructions and warning labels on the packaging container. When constructing, wear a gas mask and other protective equipment. Avoid inhaling paint mist and skin contact with the paint. 

PPE Requirements:

• NIOSH-approved respirator

• Chemical goggles + nitrile gloves

First Aid:

• Skin: Soap/water → seek medical help if irritation persists.
